ROLLING-MILL.

S pccificatiou forming part of Letters Patent No. 47,886, dated May 23, 1865.

To aiZZ whom, it may concern/L Be it Aknown that L-EL'Bnrnen' WHEELER, of Feltonville, inthe county of Middlesex and State of Massachusetts, have invented'certa'in new and useful `Improvements,in Machines for Rolling Regular, Irregular, or' Corrugated Forms in Metal; and Ido hereby-declare the following to be a full, clear, and' eXactdescription of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l represents a side elevation of a machine for the purpose. Y Fig. 2l represents a view from one` of its ends. Fig; 3"repre sents a section through a portion of the rolling-dies, to show their mode of connection with thevshafts, onl whichthey are interchangeable. Fig. 4 represents a section Jthrough a pair of rings or dies, so made as to prevent the forming of a fin' on the piece rolled by them.

. Similarletters of reference, wherethey occur in the separate figures, denote like parts in all the dra-wings.

' My invention relates7 first, to the uniting ofthe ends of the rolls that project beyond the housings with an adjustable link or yoke, to prevent them from springing or yielding as the metal'toberolled is passed between them. It further relates to the fastening of the sections of dies or rings upon the shafts by means of screw-threads cut on the shafts themselves and a nut runthereon, 'so that the screw shall expand with the shaft asV it Ver pands and continue to firmly hold the sections,'rings, or dies in place, which a key or wedge separate from the rolls or their Shafts will not do; and 'my invention further re-n lates to 4the `countersinking of oneor both faces of one oi' the4 sections'of vrings or dies andforming a shoulderor projection Aon the` neXtvadj acenlt ring or die, so thatit will enter said countersink, and thus prevent the forming of ain upon the piece of metal rolled by such dies.

To enable 'others' skilled in the art to make and use myinventiom-I will proceed to de- Scribelthe same with reference to the drawings.

AA represent the housings -in which the rollsB B are hung. 'Ihe portions of the rolls between the lhousings may be used for rolling regular, irregular, or ornamental rods, bars, blanks, &c., by means cfa series of rings or dies, C, fastened thereon, and of such form or forms as the special figure, design, or pattern to be produced may require, and that these rolls or shafts B may be readilyv removed, so

.as to change or arrange the series of Vdies thereon. The caps D of the housings are furnished withlugs a, that take over projections b on the uprights to hold them in place, the` screws E, that hold down the followers on the journalsof the top roll, aidingto thus hold said caps, and by this mode of fastening the rolls may be` readily taken, out to `have the ringsy or dies removed or replaced, as occasion may require. I propose, however, on account of the trouble of changing therings or dies when placed between the housings, to project the shafts B through and beyond one of the housings, and to arrange the rings or dies V(l on said projecting ends, as thus' they are readily removedor changed; and to prevent the thus projecting ends of the rolls from springing apart under theforce or pressure of the piece of metal passing through between them I connect the ends thereof by a link or yoke, F, and the upper end of this yoke F- should have a slot orV opening, c, anda seti screw, d', so that a bearingblock, e, in which the neck f of the upper rollrests, may. be adjusted when the space betweenthe rolls or the -over which a nut, G, is run.

I am aware that it has been proposed to hold sectional dies or rings upon a shaft by means of a key or wedge. To such holding de'- vices I lay no claim, as they will not answer my purpose.- The holding device must be a part and parcel of the shaft itself, for if separate therefrom the difference of expansion between-the shaftland the -key or wedge allows `the Sections to move, and thus make indifferent work, if not entirely give awayunderthe force; but ascrew cut on the shaft is a part of the shaft. It expands and contracts with the shaft,'and thus-under al1 circumstances remains a permanent holding mechanism. To prevent a vertical joint betweenV the Vdies at thc bottom-for instance, of a deep groove, or where a prominence is to be left on the'article rolled, I ,countersink one or both faces of one of thering dies or sections, as ath, Fig. fi, and form a projection, fi, on the .adjacent ring or die that will tit into Said countersink, and thus change the direction of the joint, or break the joint, and prevent the metal from being forced therein and form a fin upon it.

By making the dies in sections almost any conceivable pattern of metal may be rolled out with regular, irregular, corrugated, or ornamented facesA or sides; and, besides, the dies or rings are thus much more easily formed, as the contour of their peri meters may be easily made, being in rings, and nothing to preventthe free usevof tools in giving them their shapeor. form. These rings or dies are interchangeable,qand thus a few only may be so combined as to make a variety of forms or patterns. Y

The set-screws) are for changing the blocks,

' boxes, o r followers that sustain the rolls, and

to admit of their ready adjustment when the space between the rolls are changed.

H are screw-nuts run-onto screws la, cut on thewends of the shafts B, for'holding the link or'yoke F in place.`

I I`are the `gears for giving motion to the rolls or shafts.

The dies or rings between the housings may be similarly held as those beyond the housings-viz., by a collar or shoulder, B', on the shaft, and a nut, G', run up against lthe rings orsections when in place, the nut G running on a screw-thread cut upon the shaft B, as in th/e other case.

'Having thus fully described my invention, whatI claim therein as new, and desire to sevcnre by lLetters Patent, is-

l. .Uniting the projectingends of the rolls or shafts by means of a link or yoke, substantially'as and for the purpose described.
